    What is Japanese Knotweed

    Japanese knotweed is a tall, vigorous ornamental plant originally brought into the country by bthe Victorians. It escaped from cultivation in the late nineteenth century to become an aggressive invader in the urban and rural environment.

    Japanese knotweed, scientific names Fallopia japonica (Houtt. RonseDecraene), Reynoutria japonica (Houtt.) or Polygonum cuspidatum(Siebold &Zuccarini) is a member of the dock family (Polygonaceae). It is a rhizomatous (produces underground stems) perennial plant with distinctive, branching, hollow, bamboo-like stems, covered in purple speckles, often reaching 3-4 m high. The leaves of the mature plant are up to 120 mm in length with a flattened base and pointed tip and are arranged on arching stems in a zig-zag pattern.

    Two species closely related to Japanese knotweed are also found in the UK. These are, GiantKnotweed (Fallopiasachalinensis), a much taller plant which reaches a height of 5m; and a smaller compact variety (Fallopia japonica var. compacta), which grows to a height of only 1m.
